【摘要】：为了研究赤霞珠(Cabernet Sauvignon)和霞多丽(Chardonnay)葡萄植株的干物质和养分积累情况,本试验选取生长发育良好、长势一致的6年生赤霞珠和霞多丽葡萄为试材,在正常的管理条件下于萌芽期、新梢生长期、开花期、幼果膨大期、转色期、成熟期、采收期随机挖取完整的葡萄植株各3株,测定根、茎、一年生枝、叶、果实的干重以及氮、磷、钾、钙、镁、铁、锰、铜、锌元素的含量。研究结果发现:1.在整个生育周期内,赤霞珠葡萄树体的干物质积累量为172.96g/株,营养元素N、P、K、Ca、Mg、Fe、Mn、Cu、Zn 的积累量分别为 2.1154g/株、0.3374g/株、1.6249g/株、2.3872g/株、0.3584g/株、58.3566mg/株、9.5481mg/株、2.5636mg/株、9.7337mg/株。霞多丽葡萄树体的干物质积累量为207.74g/株,营养元素N、P、K、Ca、Mg、Fe、Mn、Cu、Zn的积累量分别为2.3422g/株、0.5108g/株、2.1447g/株、2.1296g/株、0.3913g/株、70.1075mg/株、10.4562mg/株、2.4001mg/株、10.8484mg/株。2.在赤霞珠和霞多丽树体中,不同营养元素在开花期和幼果膨大期积累量较多,转色期以后积累变缓。在葡萄根部和茎部,不同营养元素在幼果膨大期和转色期积累量较少,甚至出现负增长,可能是由于在该时期内,根、茎部位自身储备的营养元素也参与供应地上部的营养生长和生殖生长;但在整个生育周期内,其累积量为正值。在葡萄叶片中,从开花期以后营养元素的积累量迅速增加,为果实的生长提供物质基础。在葡萄果实内,不同营养元素的积累主要集中在幼果膨大期,成熟期内积累变缓。
[Abstract]:In order to study the dry matter and nutrient accumulation of Cabernet Sauvignon (Cabernet Sauvignon) and Chardonnay (Chardonnay), the six-year-old Cabernet Sauvignon and Chardonnay grapes, which have good growth and consistent growth, were selected as the test materials. During shoot growth, flowering, young fruit expansion, color conversion, maturity and harvest, 3 intact grape plants were randomly harvested. The dry weight of root, stem, annual branch, leaf, fruit and nitrogen, phosphorus, potassium, calcium, magnesium, iron and manganese were measured. The content of copper and zinc. The study found that 1: 1. During the whole growth cycle, the dry matter accumulation of Cabernet Sauvignon was 172.96g/ plant, and the accumulation of nutrient element was 2.1154g/ strain 0.3374g / plant 2.3872g / plant 0.3584g / plant 9.5481mg / plant 2.56366mg / plant 9.7337mg / plant. The dry matter accumulation of Chardonnay grape tree was 207.74g/ strain, and the accumulation amount of nutrient element was 2.3422g/ strain 0.5108g / plant 2.1296g / 2.3422g/ strain 0.3913g / plant 70.1075mg / plant 10.4562mg / plant 2.4001mg / plant 2.8484mg / plant. In Cabernet Sauvignon and Chardonnay trees, the accumulation of different nutrient elements was more in flowering stage and young fruit expansion stage, but the accumulation slowed down after color conversion period. In the root and stem of grape, the accumulation of different nutrient elements in young fruit expansion stage and color transformation stage was less, even negative growth, which may be due to the root during that period. The nutrient elements stored in the stem part were also involved in the vegetative growth and reproductive growth of the aboveground part of the supply, but the accumulative amount was positive during the whole growth cycle. The accumulation of nutrient elements in grape leaves increased rapidly from flowering stage to provide material basis for fruit growth. In the grape fruit, the accumulation of different nutrient elements was mainly concentrated in the young fruit expansion stage, and the accumulation slowed during the mature period.
